ADJUSTABLE MAP AND CHART SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 260,197, dated June 27,1882.

Application filed April 6, 1882. (No model.)

To all whomit may concern Be it known that I, HENRY E. HAYES, ofBrooklyn, in the county of Kings and State of New York, have invented anew and useful Improvement in Adjustable Map and Chart Supporters, ofwhich the following is afull, clear, and exact description.

Reference is-to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of my improvement, illustrating its use.Fig. 2 is a side elevation of the lower part ofthe same, shown asapplied to a table-top. Fig. 3 is a plan view of the lower part of thesame, partly in section and part being broken away. Fig. 4 is an endelevation of the hollow cylinder. Fig. 5 is a sectional elevation of thesame, taken through the line :10 a, Fig. 4, and showing the rods inplace. Fig. 6 is a plan view of the inner side of one of the washers.Fig. 7 is aperspective view of the connecting-bar. Fig.8 is a plan viewof an end part of the map-holding bar. Fig. 9 is a side elevation of thesame. Fig. 10 is a sectional end elevation of the hollow cylinder, takenthrough the line y y, Fig. 5.

The object of this invention is to promote convenience in the suspensionof maps and charts for temporary use. p

The invention consists in an adjustable map or chart supporterconstructed-with two clamps having their lower jaws connected by acrossbar provided with a hand-screw, and having eyes at their outerends, a hollow cylinder fitting hetween the eyes of the clamps, andhaving interior grooves to receive the locking-bar and holes and socketsto receive the map-suspending rods, a slotted locking-bar having a screwupon its end, washers placed at the outer sides of the clamp-eyes, and ahand-nut; also, in the combination, with the clamps having eyes and themap-supporting rods, of the hollow cylinder having interior grooves andholes and sockets, the slotted bar passing through the cylinder andclamp-eyes, and having a screw upon its end, washers placed upon theouter sides of the clamp-eyes and a hand-nut, whereby the said rods canbe readily adjusted and will be securely held; also, in the hollowcylinder having interior-grooves to receive the edges of a locking-bar,and holes and sockets to receive the ends of the map-carrying rods; and,also, in the combination, with the maps or charts, of the clamping-barshaving eyes at their ends, whereby the said maps or charts can bereadily suspended from the supportingrods, as will be hereinafter fullydescribed.

A A represent two clamps, the ends of the lower jaws of which areconnected by a short bar, 13. In a screw-hole in the center of the bar Bworks a hand-screw, O, which has a washer, D, swiveled to its forwardend to prevent the chair-back, table-top, or other support to which thesaid clamps may be attached from being injured or marred by'the saidscrew.

Upon the outer ends of the clamps A A are formed eyes E, the oppositesides of which are concaved, as shown in Fig. 3.

F is a hollow cylinder interposed between the two eyes E, and which hasits ends flared and rounded to fit into the concaved inner sides of thesaid eyes. Into the outer sides of the eyes E are fitted washers G H.The washer G has a slot in its middle part to receive the flat bar I,which has a cross-head upon its rear end to rest against the outer sideof the washer G, as shown in Fig. 3. The said edges of the bar I fitinto grooves J in the opposite sides of the interior of the cylinder F.

Uponthe forward end of the bar I is formed a screw, K, to pass through ahole in the center of the washer H and receive the hand-nut L, by whichthe various parts of the supporter are held together. Upon the innerside of the washer H are formed pairs of lugs M, to reinder F. The holes0 and sockets P are so arranged that the lower ends of the rods N willincline toward each other, as shown in Figs. 1 and 5. The upper ends ofthe rods N are bent so as to be parallel with each other, as shown inFig. 5.

Q represents the maps or charts to be sus pended, and which are securedat their upper edges between two bars, It, by nails, screws,

or rivets. To and between the ends of the bars R are secured the ends ofmetal straps, the middle parts of which are bent to form eyes S toreceive and fit upon the ends of the rods N, so that the maps or chartscan be readily suspended and removed. With this construction, byloosening the nut L the cylinder F, bar I, and washers G H can bereadily turned to bring the rods N into such a position that the maps orcharts Q can be readily seen. With this construction, also, thesupporter can be readily attached to a chair-back, as shown in Fig. 1, atable-top, as shown in Fig. 2, or other convenient support.

In case maps or charts already mounted are to be used a rod having eyesupon its ends and provided with hooks can be placed upon the upper endsof the rods N, and the maps or charts can be suspended from the saidhooks.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An adjustable chart and map supporter, constructedsubstantially as herein shown and described, and consisting of theclamps A A, having cross-bar B, hand-screw C, and eyes E, the hollowcylinder F, having interior grooves, J, and holes and sockets O P, theslotted bar I, having screw K, the washers G H, and the hand-nut L, asset forth.

2. In an adjustable map and chart supporter, the combination, with theclamps A A, having eyes E and the rods N, of the cylinder F, havinginterior grooves, J, and holes and sockets O 1, the slotted bar I,having screw K, the

washers G H, and the hand-nut L, substantially as herein shown anddescribed, whereby the said rods can be readily adjusted and securelyheld, as set forth.

3. In a map and chart supporter, the hollow cylinder F, constructed,substantially as herein shown and described, with interior grooves toreceive the edges of the locking-bar and holes and sockets to receivethe ends of the map-carrying rods, as set forth.

4. In a map and chart supporter, the combination, with the maps orcharts Q, of the clamping-bars It, having eyes S at their ends,substantially as herein shown and described, whereby the said maps orcharts can be readily suspended from the supporting-rods, as set forth.
